SASH-LOCK.

Specification of Letters Patent.

Patented Apr. 30, 1912.

L To all whom ct may concern:

Be it known that I, CHARLES N. ESTES, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented a new and useful Sash-Lock, of which the following is a specification.

This invention relates to sash locks particularly designed for use in connection with the windows of railway cars, one of the objects of the invention being to provide a compact form of lock adapted to be housed within the frame of the window and which is operable by means of a button located within convenient reach of the occupant of the car whereby the window can be quickly locked or unlocked at will.

TVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in theprecise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings :Figure 1 is a section through a portion of a window having the lock applied thereto, said lock being shown shifted out of engagement with the sash. Fig. 2 is a view similar to Fig. 1 and showing the sash locked in partly elevated position. Fig. 3 is a section on line AB "Fig. 2. Fig. 4 is a section on line C-D Fig. 2. Fig. 5 is a perspective view of the parts of the lock detached.

Referring to the figures by characters of reference F designates the window frame and G designates the movable sash to be locked. A recess f is formed in one side of the frame close to the upper end of the sash Gr and this recess is normally covered by the outer guide or stop strip H of the window, said strip being shown broken away in Figs. 1 and 2.

That stile g of the sash Gr nearest the recessed side of the frame F has a longitudinal series of notches or recesses g therein and a wear plate 1 is secured on said stile and has slots 2 extending thereinto and adapted to register with the notches 9, this wear plate being attached to the stile g in any desired manner.

The locking member is made up of a strip of spring metal bent into U-shape, said strip having an intermediate portion 3 and depending arms 4 and 5. The said arms are adapted to fit close against opposed walls of the recess f and notches 6 are.

formed in the outer edges of the arms and receive a holding plate 7 which is seated in the notches and is secured to the frame F by. means of screws or other suitable fastening devices. Arm 4 is held against movement by a pin 8 or the like extending into the frame F and serving to hold said arm 4 close against the front wall of the recess f. The other arm, 5, is free to flex, as shown in Fig. 1, and both of the arms 4 and 5, are provided at their lower ends, with wings 9 extending outwardly from the recess f and into a recess it formed in the inner or concealed face of the strip H.

An ear 11 extends laterally from the wing 9 on arm 5 and is adapted to be seated within any one of the slots 2 and project into the notch g registering with said slot as shown in Fig. 2.

A channel I is formed within one side of the frame F beyond the sash G and registers with the notches 10 in the arms 4 and 5. A rod 12 is mounted to rotate and to slide within this channel and is provided at one end with a head 13 whereby it can be easily manipulated, while its other end projects into the recess f and has a wing 14, there being a collar 15 on the rod and close to the wing 14. The arm 5 projects at its lower end between wing 14 and the collar 15 so that, by pushing rod 12 longitudinally, the collar 15 will bear against the wing 9 and cause the arm 5 to flex within the recess f, as shown in Fig. 1, thus withdrawing the ear 11 from engagement with the sash stile g and the wear plate 1 thereon. After the ear 11 has thus been completely withdrawn from engagement with the plate 1, the wing 14 assumes a position back of the wing 9 on arm 4 and, by rotating rod 12, the wing 14 can be caused to move upwardly back of the arm 4 and thus hold the lower end portions of the arms 4 and 5 in contact, as shown in Fig. 1. The sash G can therefore be raised and lowered at will. To lock the sash, the rod 12 is rotated so as to disengage wing 1st from the wing 9 on arm 4;. Arm 5 will therefore spring back toward the sash G and the car 11 thereon will move into the first slot 2 both into register therewith. This movement of arm 5 back to its normal position will cause the rod 12 to also slide back to normal position and wing 14L will therefore be brought into the space between the wings 9. By then rotating rod 12 wing 14 can be swung upwardly into recess f so as to lie between and into contact with the arms a and 5, thus preventing rod 12 from being shifted longitudinally. The sash is therefore securely held and cannot be raised or lowered until the arm 5 has again been flexed in the manner hereinbefore described.

lVhat is claimed is 1. A sash lock including spaced fixed and movable members, a sash engaging element carried by the movable member, means slidable against the movable member for shifting it out of engagement with the sash, and means revoluble into posit-ion between the two members for holding the said movable member in engagement with the sash, said last mentioned means being shiftable back of and into engagement with the fixed member for holding the movable member out of engagement with the sash.

2. A sash fastener including a U-shaped element having spring arms normally spaced apart, means for holding one of the arms fixed, a sash engaging device upon the other arm and movable with it, a slidable and revoluble actuating device, means operated by said device during its sliding movement for shifting said movable arm out of engaging position, and a wing carried by said device and revoluble therewith into engagement wit-h the fixed arm to hold the movable arm in or out of sash engaging position.

3. The combination with a frame having a recess therein and a sash having a notch therein, of spaced spring arms seated within the recess, means for holding one of the arms against movement, means upon the other arm for engaging the notched sash, an actuating device mounted to slide and rotate within the frame at one side of the sash, means on said device for shifting the sash engaging means during the longitudinal movement of the actuating means, and means upon the actuating means and cooperating with the fiXed arms for locking the sash engaging means in or out of engagement with the sash.

In testimony that I claim the foregoing as my own, I have hereto ai'lixed my signature in the presence of two witnesses.
